[@johndododoe1411]

As there's still no LPL response, here are my improvement ideas: 1. Replace the key touching ball by a standard short keypin, thus giving it a flat top on which the higher items rest. 2. Replace the ball that shifts between layers by a stack of thin master wafers. This increases the number of depths of each cut, thus allowing you to remove the side stacks that won't fit in standard form factors. Fine tuning the diameters can furter increase the number of wafer levels. 3. If the Euro profile doesn't have enough room, go for a scandinavian oval, which is still a defacto standard. 4. If you still can't get enough differs, try parallel stacks like in dimple locks, with a rectangular innermost cylinder instead of an interlocking pin.

[@SBBurzmali]

Seems like a few attacks might work. First, depending on how those ball bearings are fused, if you cranked hard enough, you might be able to snap them apart. That would allow the lock to be opened with any key, including the original one, and wouldn't be visibly destructive. Second, given tolerances are what they are, if you applied the turning force offset from the center of the cylinder, you should be able to force one set of ball bearing to engage before the other three, allowing you to decipher one set at a time, cutting the permutations down to 16 four times. Finally, depending on tolerances once again, you might be able to insert shims between the outer lock body and at least one of the cylinders, which would allow you to decode the lock and "set" it in the correct position. If you really want to get creative, you might even be able to decode the lock by sensing the fuses directly, either magnetically if they are brass like the animation indicates, or by probing each slot, assuming there is enough of a gap between the ball bearings and the wall of the chamber.

[@Rman0712]

Dunno if shimming would work, since it'd have to get around that lip in the front. Although I would love to see LPL go: "All we'll need to open this 'unpickable' lock is this shim I fashioned from a coke can"

[@SBBurzmali]

@@Rman0712 It depends on tolerances and manufacturing method, chamfered or rounded edges would give a shim a surface to turn on and with three concentric cylinders, you need to control the stacked effect of three tolerances to control that gap without binding up the lock.

[@Rman0712]

@@SBBurzmali At 2:24 it in the animation, it shows that the brown fused pins are always outside the white inner most cylinder, so the shim would have to go between the blue middle and black outer cylinders. Unless you can curve a shim on thin air don't think that's going to be possible. 😟

[@SBBurzmali]

@@Rman0712 I suspect that the brass pins are going to fall below the shear line without a key in the lock, the animation doesn't show it, but I don't see how you could ensure all 4 sets of pins aren't falling out of place without pushing them into the key a bit, that should give you some ability to either shim them in place or at least detect the fuse.

@@SBBurzmali maybe I’m misunderstanding you, but @2:25 you can clearly see the brown bearing resting on the shear line between outer and middle cylinder. Completely agree that a shim between those 2 cylinders defeats this.

[@normdyer94]

Excellent: "sets the pin positions and then cuts off access to them before you can open the lock" This uncoupling of pin set from gate trials is the essence of unpickable locks. Had locks been designed this way from the beginning, there would be no phrase nor profession of 'lock picking'. When the lock picking lawyer was confronted with another of these 2-step designs he turned to back side intrusions (not picking). You've got a great concept. Patent it quick. Smiles.

[@a-bell]

WOW, what a simple way of separating the pins from the turning mechanism. I've recently been watching other videos about impossible to pick locks and they all have this complex design that tries to separate the pins from the unlocking. Your design is so minimalistic I'm surprised no one thought about this before. I would say the only major downside is the binary coding that extremely reduces the different amounts of keys you could make with this. But either way, well done man!

Replace the ball bearings with .0030 high master wafers for the passive pins and .0060 master wafers for the blocking pins, then you will have much better key permutations.

[@psieonic]

It would, but I believe the reason for using bearings means there's no useable lip to try tension against to set pins. The balls would just slip right off. Single pin picking would be extremely difficult, even if a way is found to tension the core.

[@j3st3rxyz]

@@psieonic Can't you round off the endings of the pins?? Then you would have the advantage of using more key permutations since the pins can vary in length and because the ends are rounded they can't create a lip to tension.

[@maikeydii]

Depending a bit on the tolerances, I can see one quite easy way to defeat this lock. If there is enough gap between the outermost flange of the inner core and the body of the lock one might be able to feed in a thin, flexible shim stock between the outer rotating core and the body. Then just lift the ball stacks until you don't feel resistance from the "double ball" in way of the shim. Repeat this for all of the four locations and open the lock. Even if there's just enough space to one shim at a time, it will be quite easy to decode the biting. Also this design is really susceptible to a destructive attack by drilling the keyway just a tad larger and let the balls fall out to keyway.

[@darrennew8211]

I think the faceplate is in the way of putting any kind of shim into the lock that can reach the ball bearings. Go to 2:35 and look at the lightest color in the cutaway.

[@laurenlewis4189]

Just a reminder to everyone speculating about how to pick it: no lock is pickable by design, it's the inconsistencies in real-world machining that cause the flaws. This lock is unpickable by design (as are most locks), and there is no way to non-destructively compromise the ideal version as presented in the animation. Any locksmith/red-teamer would need a copy (or several) of the lock to actually determine where the flaws lie, and whether it's generalizable to all versions or if they must be compromised on a case-by-case basis.

[@TwinShards]

I actually had a not far off similar design in mind but would use the middle cylinder (The cylinder between the outter shell and the keyway.) to unlock. The keyway cylinder would be free-spinning when the key is not inserted. Trying to pick would be impossible because the keyway would be free to spin. Putting the key in would set all the pins then press a pin at the very bottom that would lock the keyway and the middle cylinder together if all pins are set correctly. If all pins are not already set then the 2 cylinder wouldn't lock together.

[@JMMC1005]

Super smart design. Similar in concept to the first StuffMadeHere lock, but I think your mechanism is really elegantly simple. One exploit I see would be to push the barrel backwards (without raising any pins), then strike the lock with a mallet while applying a small amount of toruqe. It would be exceptionally fiddly, but I think you could bump each of the pins above the shear line with enough patience.

[@hugoguerreiro1078]

The double bearings could get stuck on the sheer line, plus it's 4 sets of bearings, you'd have to get all of them at the same time. Seems kind of hard.

The Bowlie lock website mentions it as competition)

[@davvigtu]

That's the Yuema 750. Apparently there's been an attack on it: kzbin.info/www/bejne/m6nEc4SYf8R1gac I think this lock combined with a 750 would be very secure since it would be much harder to do a precision attack when the core spins no matter what. You would have to fix the binary bitting limitation though.

[@martylawson1638]

@@davvigtu binary bitting isn't a problem. He's already got 64000 valid codes. With a dialer checking one code per second that's still 8-9 hours to brute force the lock. Looks pretty easy to go up to 24 pins with over a million keys. Adding in the 750 spinning core mechanism to frustrate precision decoding attacks would probably get more security for the design effort.

[@fleance2k]

A tool to pick this is fairly simple in design concept. Create a key with high bitting across all lengths. At the pin locations have extendable pins in the key itself which can be lifted one ball bearing space into the lock body thus filling the first 2 chambers of the sheer core always with 2 bearings which would always open. Depending on tolerances could possibly accomplish it with high pressure air as well. Watching LPL open a lock with only an air compressor I'm pretty sure would be a new one for him.

[@tequilacollins]

Doesn't look like all 5 pins would fir in the 2nd cylinder.

[@KPbICMAH]

@@tequilacollins if you look at 2:25, you will see that all ball stacks are the same height, the only difference is the position of the double ball, which matches the key bitting. if (and only if) the lock design allows the 'pins' to be overset, you can cram the bottom two balls out of the core (grey) into the second cilinder (blue), that way neither will be prevented from moving. of course, that could not be done with a key, as you'd have to push the balls past the key hole. so tensioning and setting 20 pins in four different directions would be a formidable challenge, but certainly not one LPL wouldn't cope with.

[@tequilacollins]

@@KPbICMAH I get what you're trying to do, but to do that would require that you fit a single pin and a double pin into the outer cylinder (black), and I don't think there's room. Looking at the video, it looks like it would be close, but it's not showing the spring that also takes up room.

Lovely idea to prevent tensioning. Simple enough to mass produce. Depending on tolerances. Maybe a slim possibility of it being decodable with 4 binary keys that allow one stack at a time to be high and measuring rotation angle. But I doubt that would be reliable. Assuming 50/50 change high low, half the pins would already be set. So you only have to set 8. It's a guess that having 7 in the right spot would allow slightly more rotation and so could he measured.

[@CMDRRZulu]

Did LP ever reply or communicate a successful breach of the prototype?

[@superowl91]

instead of applying tension by turning you can do it by pushing the cylinder inward and get the pins to bind that way.

[@philippkolodziej9356]

Exactly. In the animation showing 8 of the 16 pin stacks, 6/8 are already set and the other two would act like spools, having to find the right order so set all the unset pins would be all. because all are identical spools, it would be easy to immediatelly chwck which stacks are set and which need to be raised. if you dont want to bother trying a lot of different orders to set, you could just inset a ball bearing i each unset stack and fix it with tape. and done. from there it just opens by pushing and turning.

This is a pretty great design. Since no tension can be applied to the pins; raking, ssp-ing, foil attacks, and standard impressioning won't work on it. The only thing that I can see going wrong is either over setting or under setting the pins. But for an attack like that on this lock to work, you would need to find a way to brute force the right combo. And by doing it that way, you have atleast 65440 possibilities (providing that you either go for max or min setting of the pins like binary between 0 and 1111111111111111) Overall, this seems like a pretty impressive lock

[@leogray1091]

I really think this is a better design then stuff made here. It is very smart using multiple beads instead of just a two-part pin. This allowed the inner cylinder to block the beads from moving when it's pushed in. This would really be a challenge for lock picking lawyer!.

It looks like there is some tension that can be generated when the plug isn't pushed in. The lock is annoying, but not unlockable. You'd need a rake and made a special bump key.

[@recurvestickerdragon]

Yeah, due to the tolerances of the push-to-rotate mechanism, you can probably apply just enough tension to rake/pick the pins up before pushing forward with confidence

[@poloniumdoor294]

Just hit my feed, I don't watch LPL much (more of a bosnianbill guy myself hehe) so I don't know if he's made a video yet but I'm gonna guess he'll design a bump key and bump it open. The binary pins may actually provide some challenge to bumping it though so it'll be interesting to see if that works. Great job in the lock!

[@davvigtu]

As I understand it, the typical attack against these sorts of two-stage locks is a precision measurement attack. Like in a normal lock, manufacturing imprecision means that one of the incorrect pins will bind first. You can then use something like a Sputnik pick to vary every position one at a time and discover when the lock turns ever so slightly more. Here's a video using this attack to decode a combination lock: kzbin.info/www/bejne/nmKwioqtpdZ7aNU I think you could miniaturize your design by using a tubular lock so that the second stage is behind the first stage (deeper into the lock body) rather than surrounding it.

[@timhutt7051]

Ah that is a clever attack! Probably would still take quite a while but I think it might work. I did consider the tubular design but it's difficult to fit in enough pins because you need so many.

[@davvigtu]

@@timhutt7051 Could you stack very small key pins to get a base greater than 2? If you have a key pin that's two cuts deep, and the key can have eight cuts, you could then have four of these (that would shear on any cut that's a multiple of two) with this stack pushing on an ordinary key and driver for the second stage. Perhaps the small intermediate key pins would be too flimsy or get clogged with grit after long-term use, though.

[@martylawson1638]

I think you could also do precision decoding with a set of 20-30 "test pattern" keys. Only have a vague hold on the math though so would need help figuring out the optimal test pattern. Do you have any other examples of 2-stage locks?

[@Pulse_kS]

Really Cool design and great concept. As people said earlier, it looks like oversetting the pins would be a weakness in this current design - however, I think if you made the middle cylinder hold 3 ballbearings instead of 2, this no longer becomes a problem (as you cannot lift 3 bearings and still allow the 2 cylinders to slide against each other) - the problem then becomes scaling this up to allow for more than binary pins. Either way, you would still need a special tool to be able to overset 4 rows of pins all at once, though I dont think that's an insurmountable challenge either. Love the concept either way, I'd love to see a 2.0 design, or even just other contraptions you've worked on!

[@jwrm22]

Hi Tim, Very cool and unusual lock design! I like it. I'm a board member of The Open Organization Of Lockpickers, a dedicated group of lockpickers. Our key aspects are research and knowledge sharing. Locks that have been 'impossible' for many years have been recently opened non destructive non the less. The current list is quite small of locks that can't (yet) be opened non destructively. I believe for this lock traditionally picking will not do it. But I've some other ideas... Would you sell me a copy of lock for the collection? Jan-Willem

[@timhutt7051]

I will definitely send you one, but it might take a while for me to make another one... I think davvigtu might be right about being able to pick it by precisely measuring how far you can turn the key, but it would still be cool to see it done! Is there an actual list of so-far unpickable locks somewhere or is it unwritten? Thanks for the nice reply!

[@iain3713]

Hi I was wonder how feasible it would be to have a high security lock based off tolerances alone, something using like bearings to support the cylinders, and reamed or even edm drilled pin slots. Or is this just a really expensive way of manufacturing a lock that can still be picked relatively easily.

[@jwrm22]

@@iain3713 Good question. Many high security locks rely on the high precision manufacturing but it's not only about tolerances. For example, a spool will give feedback that can be exploited no matter how good the tolerances are. Further some attacks have a higher success rate on locks with tight tolerances. Note: The Assa gin pins are a very good choice of pin for a 'zero tolerance lock'.

[@iain3713]

[@u9Nails]

The cross lock makes it more difficult to pick. But unlike a key, which may bind when inserted the wrong way, a lock picker will not be using a key. Instead they'll use tension and a smaller lock pick tool. So they'll have access to all the ball bearing and driver pins. I'm not an expert, but as long as there's some mechanism (key) being used to unlock a lock, there will always be a way to simulate that key with tools.

[@gx1501996]

[@Netasurfer]

LockPickingLawyer picks locks made of metal, all his tools are created for this, and skills probably too, if he picks a lock made of plastic, the lock will lose its original appearance too quickly, that's probably why LockPickingLawyer refuses to deal with this lock. If you can send him a metal version, then maybe he will deal with this lock. I would also suggest that you team up with Stuff Made Here, he also sent a lock to LockPickingLawyer, it looks like he is interested in this hobby.

[@brettbennett4717]

This is pretty impressive man!

[@HenrikMyrhaug]

I think if there is enough space to push the ball bearings in by the length of two balls, then you could bypass the mechanism by pushing all the double pins out of the middle cylinder. Since the balls require springs to overcome gravity, the springs will have to be perfectly fitted for each lock to prevent them from being pushed back too far, which would make it expensive to produce. A high price tag is definitely worth the added pick resistance however.

[@JohnSmith-kf1fc]

[@russellthorburn9297]

Mr. Hutt was clear. It is an unpickable lock not an indestructible one. So forget about vise, blow torch and the like. LPL will have to pick it open if it is possible.

[@kasuha]

This seems to be possibly prone to oversetting. Pushing all the balls deep enough into their channels (actually just one ball diameter deeper than the key would) will push all the double balls out of the way and the lock will turn. But it may be tricky to execute at all four sides at once and the lock certainly can be made resistant to it.

[@stinky817]

He said that it only has two possible positions for each bitting. So that makes me think that you couldn't over set them ..

[@kasuha]

@@stinky817 Oversetting always means pushing pins (or balls in this case) deeper into the pinholes than a key would. Number of possible cut depths on the key is irrelevant.

[@slashingrobin665]

Push up 1 pin stack, push in the inner core, add rotational tension, observe for slight additional rotation then pull the inner core back and check for drag from rotation. If you observe either the additional rotation or additional drag pulling the inner core out then thats your first binder otherwise reset the pins then try the next one until you find the first binding pin. Write it down. After the first binding pin is found the method changes slightly. Push the inner core in just enough to be able to set the first binding pin without it falling, then look for the next binder by pushing in an additional stack. Push the inner core in look for even more rotation or drag pulling out. If there is no additional rotation or drag pulling the inner core out, completely reset the pins then restart this portion setting the first binder again and attempting with another stack. When you find the next one write it down then start looking for the next binder with the first two set. Repeat until unlocked. It may be a little slow but since the bitting is binary, not only should you eventually pick it open but as a result you should also have to key completely decoded to be able to cut your own for future use. This is based on using the mechanism in back that prevents the outer core from turning unless the inner core is pushed in for feedback instead of the sudden movement and click from pins being set while tensioned in standard locks. The drag would be from it lining up less and less as binding pins that it catches on first are no longer blocking it allowing the core to rotate slightly further. All manufacturing has tollerences and some pins will always bind before others due to that. Thats more important to single pin picking than being able to consistantly tension it while you pick. Would love to have a copy of this to test it out, but otherwise this is mostly speculation. Love the lock design though, even if that does turn out to work it would still be pretty pick resistant. I'm not very good at writing so I'm sorry if that comes accross as word salad :(

[@jackaw1197]

One could also fix this my adding a thinner metal pin inside the spring to limit the compression even it it is possible

[@MikkoRantalainen]

@@jackaw1197 The problem with thin metal things is that they are vulnerable to bending by brute force attack. But yeah, there're multiple ways to fix the problem. For example, if the spring stack can be compressed to much, just add a regular pin of suitable length in the stack. That cannot be bent and it will reduce the available space for the compression.

[@Essence1123]

It seems to me that you wouldn't be able to hold the balls at that height unless you had a pick on every pin stack as you tried turning because there is an extra ball height in the inner core

[@Firebat45]

I have a method that I believe would pick the lock you show in your animation. There seems to be a flaw that could be easily fixed. Your design allows pins to be set to "position 0" and "position 1" with the key. With 4 special comb shaped tools along with a central tapered rod tool, you could set all pins to "position 2" and the lock would open. You can prevent this by limiting pin travel and/or placing some double height pins (like the shear line ones) at the bottom of the stack. Great work though. This is a super elegant and simple solution that I think shows a lot of potential.

[@ItsBoyRed]

That wouldn't work, in the animation the brass balls are stuck toghter, setting them all to 2 won't open it
